How many vance electrons does neon need to be stable

An element is stable when it has a full outershell.
Generally, most shells after the first can hold 8 electrons.
The first shell can only hold 2

So in order for neon to be stable it must have a full outer shell
The first shell can hold 2
Neon has 10 electrons
10-2=8
The second shell can hold 8
And neon has 8 electrons left

So it must have 8 valence electrons to be stable

I’d have to say no because without oxygen in the water the fish would all be dead. so if you want to fish for dead fish, pick the ponds with the lowest oxygen concentrations.
